dts <- cut(pc$active_power, breaks = 4)
model <- vlmc(dts, keep_match = TRUE)
print(object.size(model))
model <- trim(model)
## memory use should be reduced
print(object.size(model))
nm_model <- vlmc(dts)
print(object.size(nm_model))
nm_model <- trim(nm_model)
## no effect when match positions are not kept
print(object.size(nm_model))
